I believe that the first 100 folders were going to be numbered. Mick posted in another forum that all of the first 100 would soon be out. In that 100 there have been several different handles (G10 finished a little differently, all the same basic shape) and some are hollow ground and some flat ground. So I guess that all ARs and GBs that are currently in circulation are numbered but pretty soon that will change. Anybody who knows more, feel free to correct me. Also, the number on the knife doesn't neccesarily tell you what order it was made in. If someone ordered a higher number then someone else ordered and lower number, they would be made by order sequence, not number sequence. BTW, I have AR #19 and GB #85.
